Like millions of other people I own an iPod. I bought it a few years ago, not because I feel the need to own everything with an Apple logo on it, but because it's small, very portable and because I like the ubiquitous support for car connections and the myriad of accessories. In short it's the ecosystem around the product that makes it so attractive, not what Apple created in the hardware. And it's certainly not what Apple have created in the software either.

I dislike the perceived requirement to buy into the whole Apple experience just to use my 8GB music player, and iTunes is the pinnacle of my dislike. I'm not going to get on my box about how inflated and overpowering the software is, because I don't need it. I don't buy music from Apple and I have a product that doesn't support video or Apps, i just want to put music onto my music player and have it do the job it was made for.

So I wanted to share an alternative called SharePod. Now I don't have any affiliation with SharePod or its author but if you too own an iPod for the purpose of playing music, then I recommend you download it and try it out. It's free, lightweight, and you don't even have to install it, it works straight off as an executable. I like the no nonsense way it instantly displays the music already on the device, and allows me to drag and drop my DRM-free mp3s onto it. You do still need your proprietary white cable though!

It seems another Icelandic volcano called Grimsvotn has started erupting last night. The airespace in Iceland is closed (justice!) but the ash cloud is heading in a north westerly direction at a height of 12KM so it shouldn't impact European flights if it stays like that. The Met Office shows the ash cloud from volcano Grimsvotn

When the words "Wifi" and "Cloud" are used in the same sentence, it's usually in reference to a ubiquitous provider based in St Albans. But although they may have picked a cool name, there is growing merit to the idea of providing Wifi for enterprise customers as a service, just like web hosting is today.

What it means to the enterprise customer base is that the management and cost of deploying an enterprise class wireless network is largely reduced or at least spread over time, and the risk of hardware obsolescence and the squeeze on controller bandwidth becomes less of an issue.

So why hasn't this method of deploying WiFi been done before? It's largely down to the manufacturers ability to support this type of deployment architecture, that was until recently based on sending WiFi traffic back to a centralised cluster of controllers where is was processed, marked, dropped, prioritised or spat out to its destination. Up until 12 months ago, this was the norm and claims of this architecture being a bottleneck were met with marketing sneers. But as is always the case with technology vendors, a lousy feature is only lousy until it has been implemented, and now the bottleneck problem magically exists. To give them credit, it wasn't really until 802.11n started becoming more widely deployed, that controller bottlenecks were a real world problem. However, the combination of 11n and the fact that most enterprises were recognising the cost benefits of architecting distributed wifi networks, has meant that distributing real intelligence to the APs while maintaining command and control in the centre, is probably the way forward - for now.

So if your friendly IT supplier knocks on the door and starts talking about WiFi as a service, what are they trying to sell you? First of all, only 2 hardware vendors currently offer solutions that you could truly call "Cloud WiFi". Motorola and Aerohive. Both have access points with enough real intelligence to filter, firewall, inspect, process, switch frames and route packets and perform RF management functions without the constant need for a controller, and both have features that allow the slicing and dicing of controller functions for different end customers. In both cases, the controller is out of the data path, and acts only in a configuration and policy management function, and this means it can be hosted anywhere. In most cases, the end customer has firewalled access to his or her own policies, rules and statistics and shares the cost of the hardware and software with other like minded IT managers through the WiFi Service Provider. They may even lease the AP hardware.

Personally I can see this working in principal, but there is one sticking point for me. Just as Cpanel and Plesk allow the user of a shared hosting platform to perform common tasks without worrying about the underlying platform, so there needs to be a equivalent for managed, hosted WiFi. In that way, the end customer can choose and change the colour and brand of the APs they want hanging on the ceiling, and not be concerned about learning a new, complex and vendor specific configuration back-end. Believe me, the complexity of configuration is going to get worse before it gets better, and by then, we'll have a new architecture paradigm anyway. Anyone for fat APs?

The disruption caused by the fire continues, with roads still closed around the whole area. To get to Bracknell from Crowthorne last night we had to drive all the way to Jennetts Park near the A329M and then back on ourselves past the Waitrose depots. Many road closures are manned by police, who seem happy to talk to people about the events of the day. Several residents have spent a second night away from their houses after being evacuated, I feel for them and hope they get back to their intact homes soon, ready to start clearing the smell of smoke which has soaked everyones clothes and houses.

We went for a walk last night into Wildmoor Heath, around the back of our house, and although there have not been any major fires here, there were some small places with charred trees and fences. The place was unusually quiet, with less road noise coming from the closed bypass and a stillness in the air that we hadn't experienced for a number of days. With the wind dying down a little, we hope this will help the fire fighting effort which is still very much ongoing.

On a practical level it seems that schools that were closed yesterday, have re-opened today. I respect the decision was made with good intentions, but was it really necessary? Was it smoke and wind direction or was it to keep traffic off the roads? Let me know what you think.

The Daily Mail, in true Daily Mail fashion, has grasped the story too, focusing on how close the fire came (has come?) to Broadmoor. Can you imagine the operation if they had to evacuate that place?

Of course, we continue to hear about the hard work and dedication of the people that are fighting this fire on the front line. They all deserve huge recognition. The Golden Retriever pub which was evacuated on Monday - not least because it has a thatched roof - has been turned into the Fire and Rescue HQ offices. The pub is obviously closed to the public, but it is now patronised by fire fighters during their well earned breaks. I couldn't think of a nicer place to re-group and refresh.

Finally, lots more photos emerging from people, some of which are very good. I haven't been out with my camera yet, I was going to focus (no pun intended) on the aftermath, when it finally dies down. Two good sets of photos from other talented people, not me.

I've had a dropbox account for a few months now, and it's probably the most used web service / piece of software on my laptop. If you're not familiar with Dropbox then let me explain. It's a small piece of software that you load on your PC and it creates a folder, just like any other, that will sync everything you put into it, with a secure service on the Internet. If you have more than 1 PC and you load Dropbox onto them all, then those files will be in sync across all your computers. Although maybe not its primary use, it's a really easy way to copy files between computers at home or home and work. It also acts as a secure way to backup any important files, and to share files between other people who may or may not have a Dropbox account. I use it every day to copy files between computers and to share individual files that are too big to email.

To start with, you get 2GB of storage for free, but you can earn more by referring friends. Each one you refer gives you and them, and extra 250MB. If you want to sign-up, use this link to get yourself (and me!) and extra 250MB right from the start.

For the geeks like me out there, there are also apps for Android and iPhone devices that makes copying files off your phone to your PC (photos and music for example) really easy.

Update: Because I run a server at home, I'm now running Dropbox as a service on that server. It means that my files in Dropbox will sync to my server, even if I'm not logged in. Neat. I got help from this post.

So far today, I've not seen any reports of the fire getting worse, but there is traffic chaos around the area because of the road closures. Avoid it if you can or find an altrernative route in advance.

Regular readers may have realised from previous blog posts that we live in Crowthorne. We're lucky to live in a very green area, but today there have been major fires in some of the forest surrounding the village. From our house towards the south of the village, we can see a lot of billowing white and grey smoke coming from Swinley Forest (also sometimes known as The Lookout). The air is thick with the smell of smoke and even though we are still some way away, the view of trees in the near distance is obstructed because of the smoke. The sound of sirens has been heard throughout the day and there have been several major road closures leading to restricted access in and out of the village. Some other local residents have managed to get some pictures of the damage and ongoing fire. The photos below are courtesy of Ian Emery.

Update 22:40: Personal reports from people on Facebook and Twitter are saying that the fire has spread across the Crowthorne bypass and towards the car park near Broadmoor. There are 20 engines in attendance, some from as far away as Feltham.
